SPECIFICATION forming part of Letters Patent No. 464,717, dated December 8, 1891.

Application filed November 29, 1890. Serial No. 373,034. (No model.)

T @ZZ whom it may concern.-

Be it known that I, HENRY RUPPEL, a citizen of the United States, residing at Cleveland,in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in I-Iydrocarbon-Burners, of which the following is a full, clear, and complete description.

The invention relates to a hydrocarbonburner erected upon a pan or shelf, said shelf being perforated, as hereinafter shown, and the burner being of the form and construction described, whereby the iiame from hydrocarbon burning in an open annular chamber at the base of the burner rises direct from the exposed fluid through a flue formed by two perforated chimneys, producing a blue of said lighting attachment.

flame and consequently an intense heat, resultant from the admission of air on both sides of the combustion-chamber and through the center, as hereinafter fully set forth.

That the invention may be seen and fully understood, reference will be had to the following specification and annexed drawings, forming a part thereof, in which- Figure l is a vertical section of my improved burner. Figs. 2 and 3 are detached sections hereinafter explained. Fig. 4 is an enlarged cross-section of part of an annular conduit forminga part of my improved burner, showing the attachment for lighting in cross-section. Fig. 5 is an enlarged side view Fig. 6 is a sectional view of a portion of the supply-pipe. Fig. 7 is a plan View ofmyimproved burner, showing the cut-otf-valve mechanism in connection therewith. Fig. 8 is a longitudinal vertical section of said eut-off valve. Fig. 9 isa detached View hereinafter described. Fig. 'l0 is an elevation of the burner; and Fig. 1l is a perspective view of a port-ion of a stove, showing the position of the burners, one being tipped to show the perforation in the panor shelf.

Like letters of reference designate like parts in the specification and drawings.

The importantparts of my invention are best shown in vertical section in Fig. l. The burner rests on a pan or shelf A, and consists of the outer casing B, which is substantially of the form shown in drawings, daring at the base, as indicated at a. The casing B is riveted, bolted, or otherwise attached around its upper edge to the cap C. The outer portion ab ofJ the cap C is connected with the central portion c by the arms d CZ d d, Figs. l, 7, and l0, the entire cap, including the part c, part b, and 'the arms d. d d CZ being preferably one piece. Within the casing B, near the base thereof, is arranged an annular conduit D. Said conduit is of the form shown in cross-section in Figs. l and 9. Figs.2 and 3 are plan views thereof, showing two different styles which may be used. This conduit D is made of spun brass or its equivalent and is 'of one piece, as shown, having two flanges e and f raised thereon, the flange e being on the outside of the opening g, Fig. 3, (or the openings g', Fig. 2, if that form is used) and the flangef on the inside thereof. To these two ilanges c and f are attached two perforated chimney-walls E and F, which extend up and are attached at their upper edge to two corresponding flanges h and z', Fig. l, on the cap C. The space between the tops of the two chimney-walls E and F is open, with the exception of that part taken up by the arms (l, as shown in Fig. 7. A third wall G (not perforated) is attached to the cap C and extends down inside of and concentric to the wall E to a point near the line of the upper edge of the ilangef, forming an air-induction tube in the center of the burner in open relation with the interior 0f the cap C. The space between the tops of the walls G and E is closed, as is also that between the wall F and the casing B. A crosspiece j, Figs. l, 2, E3, and 9, is attached to the annular conduit D, and a bolt 7o, passing down through the center of the cap c and the airflue G, through the cross-piece j, having a nut Z on the lower terminal thereof, secures rigidly together the various parts of the burner hereinbefore mentioned.

Extending outward from the annular conduit D, preferably from the front, is a projection H, Figs. 2, 3, 4, and 5, preferably an integral part ot' said conduit. The purpose Said extension is constructed as shown in Fig. 4, having a cover m, hinged thereto.

Attached to the cover m, depending therefrom on the inner side, is a shelf n, substant-ially of the forni shown, and covered with a layerof asbestus or its equivalent o.

Connected with the extension Il is the induction-pipe p. lVhen the cover mis raised, as shown by dot-ted lines, Fig. 4, the shelf n will become filled with hydrocarbon. It is then lighted and closed, when the hydrocarbon runs down into and around the annular conduit D, where it burns, thereby heating Said annular conduit. rlhe llame direct from the liquid hydrocarbon thus burning rises in the annular tine E', between the two chimneywalls E and F, in direction of arrow l, Fig. l. The air passing through the perforations in the pau and r-ising on both sides of said annular flue causes combustion in said tine, which develops a blue 'flame and intense heat.

The pan or shelfA is perforated under each burner, as shown in Figs. l and 1l, having a large `hole q in the center and a series of smaller holes r circuinscribing it just inside the flaring y portion a. The air passing up through these perforations, as above stated, causes combustion to take place in the annular flue `E between the chimney-walls E and F, resultant from said chimneys bein g perforated. Air also passes up through the airinduction tube or central ilue G into the chambered cap c,escapingtherefrom through the holes s in said cap, thereby causing intense heat at the top of the burner.

`The induction-pipe p is covered with asbestus or its equivalent t, held in place by a sheetiron sleeve u, thus keeping the hydrocarbon cold in the pipe p. rllhe flow of hydrocarbon through said induction-piliie is regulated bya valve I, of which Fig. 8 is a vertical section. The valve is operated by the arm J, having a lug 'u on the under side thereof, said lug working in a semicircular groove w, Fig. 7. The opening and closing ol the valve is regulated by the `stops fr.

The [iow of hydrocarbon can be so regulated by the use of the stops a; a" as to obviate a great danger which has heretofore eX- isted from leaving the valve open when the burner is not lighted, (particularlywhere gasoline is used,) thus allowing the liquid hydrocarbon to overflow. lly the use of my iniproved burner and cut-off valve the stops a; 0c can be set to supply a sufficient amount of gasoline or hydrocarbon, and at the Sametime should the valve be opened to its full capacity and the burner not lighted the overflow will be so slight that it will vaporize as fast as it overflows, thus avoiding a great danger and producing a saving of fuel. The tank can be placed even with, above, or below the top of the stove, as may be desired, the elevation of the tank in order to produce a sufficient pressure, as required ordinarily, not being necessary with rny improved burner.

My improved burner is not alone valuable for cooking purposes, but also as a heater. The burner, being of the saine form and construction, can be made larger than that necessary for cooking, when the outside casing B will forni a large area of radiating-surface.

l ain aware that the use of two perforated chimneys arranged concentrically one within the other is not new. I utilize the perforated chimneys in combination with the various other parts of my invention.

Having described my invention, `what I claim as new, and desire to secure by Letters Patent, is-

l. In a vapor-stove, the combination of the annular conduit D, the projection l-I, having the in d notion-pi pe p connected therewith, and a lid pivoted thereto, said lid having a shelf depending therefrom covered with asbestus or its equivalent and arranged as described, whereby on the raising of the lid the hydrocarbon flows onto said shelf and when closed runs into and flows around the annular conduit, substantially as and for the purposeset forth.

2. In a vapor-stove, the combination of the perforated pan A, the outside casing B, the perforated chimney-walls E and Rinoa-perforated wall G, the annular conduit D, and the valve connection therewith arranged in the manner set forth, whereby high `heat is generated from the liquid fuel within the flue E and at the top of the burner, substantially as specified, and for the purpose described.

3. In a hydrocarbon-burner, the inductionpipe p in open relation with theannularconduit and lighting-cup Il, said conduit formed from one piece with openings on the upper side, in combination with the perforated chimney-walls extending upward concentrically one within the other on cach side of the openings in said conduit, operating conjointly with an inner non-perforated wall in open connection with the chamber of the perforated cap c, arranged substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY RUP'PEL.
